18:04
Add support for measuring and reporting coverage of the parser state machine using the SQLITE_TESTCTRL_PARSER_COVERAGE test-control. check-in: 1253a872 user: drh tags: lemon-improvements
14:46
Faster and smaller implementation of sqlite3AtoF() based on a suggestion from Cezary H. Noweta. check-in: fd2e0e7a user: drh tags: trunk
14:32
Fix crashes that could occur if SQL NULL values were passed to the built-in FTS5 snippet function. Edit: breaks amalgamation builds. check-in: 6a790b67 user: dan tags: trunk
14:30
Add options to speedtest1.c and speed-check.sh for testing performance of floating-point computatations. check-in: ebfea872 user: dan tags: trunk

2017-12-25
13:43
Fix an assertion fault on a syntax error input caused by check-in [6b2ff26c25bb9da3]. Problem discovered by OSSFuzz. check-in: 90d6e4f1 user: drh tags: trunk
04:15
Enhance LEMON so that it generates the action table in such a way that no range check is needed on the lookahead table to verify that the next input token is valid. This makes the lookahead table slightly larger (about 120 bytes) but helps the parser to run faster. check-in: 7eb0198d user: drh tags: lemon-improvements
00:10
In the LEMON-generated parser, avoid unnecessary tests for the acceptance state. check-in: fdbb35c5 user: drh tags: lemon-improvements
2017-12-24
23:38
In the LEMON-generated parser, rearrange the meanings of integer action codes so that reduce actions occur last. This means that the most common case (reduce actions) can be recognized with a single comparison operation, thus speeding up the main parser loop, slightly. check-in: 7bfe7a36 user: drh tags: lemon-improvements
18:56
Fix a NULL pointer dereference after a syntax error that can occur as a result of check-in [6b2ff26c25bb9da3] yesterday. This problem was discovered by the OSSFuzz. check-in: d49afb8f user: drh tags: trunk
17:06
Improved parser tracing output. check-in: 25be5750 user: drh tags: lemon-improvements
17:01
Grammar changes: the sclp non-terminal should always be followed by a scanpt. check-in: 74a0181f user: drh tags: span-refactor
14:14
Improved parser tracing output. check-in: c4951833 user: drh tags: span-refactor
00:18
Remove the ExprSpan object. Instead, keep track of the test of subphrases in the parse using the "scanpt" non-terminal. check-in: 3eab7bdc user: drh tags: span-refactor

12:33
Move the generation of output column names earlier in the case of a CREATE TABLE AS. This is a fix for ticket [3b4450072511e62] and a continuation of check-in [ade7ddf1998190b2b63] that fixes cases of ticket [de3403bf5ae5f72ed6] that were missed previously. check-in: 6b2ff26c user: drh tags: trunk
11:51
Add a SELECTTRACE() macro to indicate when column names are assigned to a SELECT statement. This helps with debugging for tickets like [de3403bf5ae5f72e] and [3b4450072511e621]. check-in: 8f194008 user: drh tags: trunk
2017-12-22
19:53
In the sqlite3TreeViewExprList() routine, show the "AS" alias name for each expression in the list, if it exists. check-in: 5efd854f user: drh tags: trunk
00:52
Modify the new sqlite3_vtab_collation() interface so that it takes a pointer to the sqlite3_index_info object passed into xBestIndex rather than an sqlite3 connection pointer, which the xBestIndex method might not have access to. check-in: 5c1fe666 user: drh tags: trunk
2017-12-21
21:41
Fix SQLITE_DBCONFIG_TRIGGER_EQP so that it works even if SQLITE_DEBUG is not defined. check-in: afbbfff7 user: drh tags: trunk
21:02

18:23
Change the name of SQLITE_DBCONFIG_FULL_EQP to be SQLITE_DBCONFIG_TRIGGER_EQP (which we can do without breaking compatibility because the former name has not yet appeared in an official release) and streamline its implementation. check-in: fffc7685 user: drh tags: trunk
14:46
Add the SQLITE_DBCONFIG_MAX preprocessor macro which will always be equal to the largest SQLITE_DECONFIG value. check-in: 95d41033 user: drh tags: trunk

2017-12-16
20:20
Add an experimental location(X) SQL function that attempt to return the location of the payload within the database for the record that contains column X. location(X) returns NULL if X is not an ordinary table column or if SQLite cannot figure out the location because it is using a covering index. check-in: 51be9558 user: drh tags: location-function
19:36
Add the sqlite3_vtab_collation() function, which allows an xBestIndex callback to determine the collation sequence that SQLite will use for a comparison. And the SQLITE_DBCONFIG_FULL_EQP configuration option, which enhances the output of "EXPLAIN QUERY PLAN" so that it includes statements run by triggers. And the code for the sqlite3_expert extension and command line application. check-in: 4c782c95 user: dan tags: trunk

Fix typo in help information for an FTS5 script. check-in: 777ae800 user: mistachkin tags: trunk
20:25
The top of an index equality loop normally starts with OP_SeekGE and OP_IdxGT. This check-in adds a flag to OP_SeekGE such that it fails immediately if the key is not equal, then jumps over the OP_IdxGT, saving a call to the key comparison functions. Consider this check-in a proof-of-concept. It needs improvement before going on trunk. Some tests fail, but only because they new use fewer key comparisons than expected (which is a good thing!). check-in: 32e31b9b user: drh tags: seekeq-experiment
